Usenet Newsgroup Descriptions

Various kinds of newsgroup descriptions are maintained
in different places around the Internet. There are
three main places you can look for newsgroup descriptions:

Charters. Some newsgroups regularly
post a description to the group that describes its intention. These descriptions
are
posted by the people involved with the newsgroup creation and/or administration.
If the group has such a description, it almost always includes the word "charter",
so you can quickly find it by searching the newsgroup
for that word.

newsgroups collected by JumpJet
